Abstract

Cable-stayed bridge, including a span placed on the supports and connected to it by cable-stayed pylon, mounted on a support, characterized in that the span is attached to the support by a hinge with a horizontal axis of rotation.

Description

VANTovy bridge

The proposed conspiracy solution is worn out to the area of my building and can be used by the State Pharmacopoeia of erecting bridge crossings over water and other obstacles.

Known cable-stayed mosses, including a span placed on supports and connected to the train via a cable-stayed pylon, are mounted on a support (see, for example, the book: Mzsts and tunnels on railways, under the re-record Osipova V.O.M., Transport, 1988, p. 8).

The closest to the claimed constructive solution is a cable-stayed bridge, including a span placed on the supports and connected to it by means of a cable-stayed pylon mounted on a joint (see book: V.K. Kachurin, Design of hanging and cable-stayed joints, M., IS7I, p. 14, Fig. 1.12.).

The disadvantage of this Shch) ototype, as well as the above

analogs are the high complexity and material consumption of the construction of the cable-stayed bridge. This is due to the fact that for the installation of the superstructure, it is necessary to build a resident intermediate support. The latter also constricts the river bed, which complicates navigation and the passage of water.

This constructive solution is aimed at solving the problem of reducing the complexity and material consumption of the construction of a cable-stayed mine.

The solution to this problem is achieved by the fact that in the cable-stayed bridge, including the span placed on the supports and connected: with it, by means of a cable-stayed pylon, mounted on the mouth, the span is attached to the support by means of a hinge with a horizontal axis of rotation.

The applicant is not aware of constructive solutions that have the same set of essential features as the claimed one, which indicates that the claimed object meets the criterion

novelty.

Thanks to the implementation of the distinguishing features of the claimed constructive solution in conjunction with the driznakash common with the prototype, a new technical result is achieved - there is no need for xojDHMocTb in the construction of a temporarily intermediate support in the process of bridge construction.

The essence of the proposed utility model is illustrated by drawings, where FIG. L shows the ith stage of the construction of the bridge span, FIG. 2 shows the articulation of the span with the abutment on which the pylon is mounted; Fig. 3 illustrates the P-ok final: the step of erecting the span, Fig. 4 shows a general view of the proposed cable-stayed bridge, Fig. 5 shows a diagram of the bridge in operation.

A cable-stayed bridge contains a span I with a transverse beam 2, placed on supports 3. Using a cable-stayed bridge 4, the span I is aligned with pylon 5 (in this particular case, the p-bridge is shown: pylon), using a hinge 6 with a horizontal axis of rotation with a support 7, on which the pylon 5 is mounted using braces 8.

In the process of erecting a bridge of a predictable structure, a span: the building I is mounted in two stages. First, only a part of it (for example, half) is erected together with the transverse beam 2 (see Fig. 1).

The mounted part of the span structure I, by turning around the horizontal axis of the hinge 6, is set to the design position and, with the help of cables 4, is connected to the pylon 5, fastened to the abutment 7 with singing guy wires 8. The remaining part of the span structure I is mounted by moving along its already completed part. Wherein

there is no need. six in the construction of the intermediate support, because its role is played by the part of the structure built at the first stage. This makes it possible to significantly reduce the material and labor costs associated with the construction of the bridge, as well as eliminate difficulties in navigating and missing water.

The design works as follows:

The efforts from the weighing rod assembled from two parts of the span structure I and the payload located on it are transmitted to the guy 4 through the transverse bazha 2 to the pylon 5, the head of which (not shown separately) is fastened to the abutment 7 using braces 8. At the same time, one-sided horizontal the compression force in the span structure I is perceived through the hinge b concrete1 with an absorptive abutment 7, which makes the equilibrium of the system statically unchanged.

The span I under the influence of load and temperature bends Cm. Fig. 5). The deflection of the span structure is limited by cables 4, fastened to the transverse beam 2 and the pylon о, the movable support 3 allows for horizontal interleaving of the span I.

The proposed construction can be used at the bridge. It will reduce the material consumption and the complexity of the construction of cable-stayed bridges by eliminating the need for the construction of intermediate supports.
